Truncate Channel

Truncating a channel removes all messages but preserves the channel data and members. To delete both the channel and its messages, use Delete Channel instead.

Truncation can be performed client-side or server-side. Client-side truncation requires the TruncateChannel permission.

On server-side calls, use the user_id field to identify who performed the truncation.

By default, truncation hides messages. To permanently delete messages, set hard_delete to true.

Truncate a Channel

await channel.truncate();

// Or with parameters:
await channel.truncate(
  message: Message(text: 'Dear Everyone. The channel has been truncated.'),
  skipPush: true,
);

Truncate Options

Field Type Description Optional
truncated_at Date Truncate messages up to this time
user_id string User who performed the truncation (server-side only)
message object A system message to add after truncation
skip_push bool Do not send a push notification for the system message
hard_delete bool Permanently delete messages instead of hiding them
